3.4 Configuring the Instrument

The ORBISPHERE 3650 analyzer can be readily configured for your application using the following commands in the Configuration menu. The instrument must be connected to your PC in order to change its configuration.

3.4.1 Automatic Data Acquisition - Setting Sampling Intervals

The analyzer can perform as a standalone data acquisition device, automatically recording gas measurements with the date and time, and storing up to 500 of these values. Choosing the WinLog97 program's Configuration, Sampling Rate menu lets you select time intervals (acquisition rate) for this storage capability.

Use the slide bar to view and select a sampling rate, from 15 seconds to 1 hour. The selected rate is shown in the Acquisition rate window.

Click OK to save this rate. Once your choice is made, the analyzer can be used independently of the WinLog97 program for data acquisition, as described in “Automatic Data Acquisition” on page 16.

Fig 3-9: Automatic Data Acquisition

Note:

The Acquisition rate set via this menu is independent from the monitoring chart updating rate described in “Monitoring Measurements In Real-Time” on page 21. The sampling rate menu applies only to automatic data acquisition, while the chart updating rate is used only for displaying real-time results via the monitoring chart.

3.4.2 Membrane Selection

You may find it necessary to use a different type of membrane for different applications. Naturally, with any membrane change, you will need to re-calibrate (see “Sensor Calibration” on page 32). You should also consider the changes in required flow rates and response times, which are specified in the accompanying EC Sensors - Maintenance & Installation Manual.

To re-configure the analyzer, choose Configuration, Membrane to bring up the box which reveals the membrane models available.

Choose OK when the desired membrane is selected.

Note:

Only those membranes applicable for your instrument model can be selected. All other membranes are grayed out.
